They aren't Sudanese, but maybe they're not from Syria. They are middle Eastern in appearance, not African. Not sure if not Syrian, but that's what we've heard.
Regardless, they are virtually all single men living together.
Locally, there are hundreds of single Somalian and Syrian men. One apartment complex in GI is nothing but Muslim men. A couple of parks in town had to put up cctv to monitor the drinking/drugs/fights.
Anecdotal I know.
I, as always, am speaking of illegal immigrants. You are talking about legal newcomers. I am very pro legal immigration btw, as stated here many many times.
Big difference.
